[PATCH] peci: fix potential memory leak in devm_adev_add()

[Jianglei Nie]

devm_adev_add() allocates a memory chunk for "adev" and "adev->name"
with adev_alloc(). When auxiliary_device_add() fails, the function calls
auxiliary_device_uninit(), which doesn't release the allocated "adev"
and "adev->name", thus leading to a memory leak bug.

We should call adev_release() instead of auxiliary_device_uninit() to
release the "adev" and "adev->name".
